3-(3-Tert-butylphenoxy)benzaldehyde → 1-butyl-2-{3-[3-tert-butyl-phenoxy]-phenyl}-6-(2-piperazin-1-yl-ethoxy)-1H-benzimidazole

Participants

Reaction Steps

A mixture of 1-BOC-4-[2-(4-amino-3-butylamino-phenoxy)-ethyl]-piperazine (synthesized via General Procedures G1 and G2 and H) (0.130 g, 0.512 mmol) and 3-(3-tert-butylphenoxy)benzaldehyde was subjected to General Procedure K. Reaction was concentrated and purified on silica gel-chromatography using DCM-2% MeOH/DCM. The BOC-group was removed employing General Procedure T1 to give 1-butyl-2-{3-[3-tert-butyl-phenoxy]-phenyl}-6-(2-piperazin-1-yl-ethoxy)-1H-benzimidazole (0.10 g).
